ZA Firewall Log - Behumbled

I am getting attacks like crazy, and they are all rated high. I noticed recently on both computers, that once in a while I can access the internet on certain programs but my browsers will not load any websites. It is so random it is hard to explaine. But I wanted to post a firewall log as It seems like they are using my ip to send packets or other raw data back to my router and my other comp, it is happening very frequently. I also have a nintendo wii on my router wirelessly of course. But it is usually off. I noticed about one hour ago, that in mIRC it will connect to the server and I cannot join any channels, ive done everything like changing my nickname registering releasing nickname indentifying, everything. It is being pretty obvious that some hacker is slowly monitoring my system, and my IP or Mac adress, and he/she can do as they please with any program. Because usually it's only the programs that I regularly use ie, norton, zone alarm, mIRC, Counter Strike-Source which I can no longer query any servers. I also reformatted my computer about 4 days ago.. that should get rid of a virus for sure especially being that I have reformatted about 6 times sense I had this computer and it doesn't seem to be doing me any good. No matter what computer I get the same thing happens, what did I do that is so important to these people? is there a way to track them? because I am convinced it isnt a virus it is some experienced hacker. any ways here is the log,
